You have a few that look like they are working. Not bad for being inexperienced, not great for someone that has been growing for 12 years. Humidity looks low. Some of them look like they are flowering.
Are you cloning autos? I mean, it can be done. It's a lot of work chief.
I would crank up the CO2 and humidity (foliar spray with seltzer water, if you don't have a fog machine), swap out the rez, toss the flowering cuttings, or at least snip the buds off as well as your yellowed leaves at their base. I take the time to snip off browning parts of leaves too. I'm sure there are plenty of people on here that would argue against everything that I stated, but I get better than good results in less than two weeks.
